Cmos logic IC inputs must never be floating. Your CD4017 IC has its EN and R inputs floating. They MUST be at a certain logic level.
I agree that you did not read the datasheet for the CD4511 and have probably destroyed it by missing the output current-limiting resistors.
The CD4511 is designed to drive ONE display but your circuit has four displays in parallel. The LEDs in the different displays do not match so some will be very dim or will not light. Why not use a CD4511 with current-limiting resistors for each display?
